Ratings Breakdown:
The Minnesota Vikings’ victory over the San Francisco 49ers, 32 to 31, on NFL Preseason Football led NBC to Sunday overnight household victory with an estimated 4.7 rating/8 share from 8-11 p.m. ET. Comparably, this was a 12 percent increase over the 4.2/ 7 for the preseason match-up on the year-ago evening. As a reminder, overnight results for any live sporting event are always approximate.

On CBS, summer young adult demographic attraction “Big Brother” was close to year-ago overnight levels, with a second-place 4.0/ 7 from 8-9 p.m. Comparably, that tied competing “Celebrity Family Feud” on ABC and the end result this week will, hopefully, result in one of these floaters getting evicted. Note to any future houseguests: floating can only get you so far. It is the big moves that count on “Big Brother.”
